Ipe Clip® Installation

Use when fastening edge-groove clips or when top-down face screwing on either wood or metal joists. Its universal versatility easily adjusts to fit 1-1/2” to 3.5” wide joists and utilizes a cam-lever action pushing up to 1,100 lbs. of force. This rapidly increases on-site deck installations with more efficiency over typical pry bars or chisels.

Give yourself the freedom you need with a deck tool that delivers true "One-Man, One-Hand Installation" capabilities. Simply set your deck boards in place to install hidden deck fasteners or face screws. When an unwieldy board comes your way, place the Hardwood Wrench Jr. (or Hardwood Wrench) onto a joist in either single and double joist configuration, and slide it up the joist so the locking cam touches the edge of the warped board. Effortlessly swing the handle upward to lock the board into a straight position, locking the board in place. Now continue fastening the deck board. It’s that easy!

The Hardwood Wrench Jr. saves time installing deck fasteners on the professional job-site, or on a weekend deck project at home.

US Patented

Our advanced and patented technology utilizes a rotating, locking cam coupled with an elongated dog-leg which stabilizes and locks this tool into place. Additionally, there are no uncooperative wheels, dials, clamps, or flexible tubing that can slip or spin off the board or joist, making the installer stop fastening just to reset the tool again, and again.

Its hardened steel handle is strong and the solid steel gripping joist pins provide anyone installing a deck the ability to straighten deck boards from both left- or right-hand direction. This is especially useful when straightening a board on the outside of the deck frame.

8 Configurations

  1. Right hand single joist
  2. Right hand double joist
  3. Right hand reverse handle single joist
  4. Right hand reverse handle double joist

We loved the Hardwood Wrench Jr.! This tool gave us so much confidence to build our cabin deck. It was just me and my wife installing the deck and we couldn't be happier how fast the wrench slid into place and moved the boards where I needed them. Andy Lichter (Cedar Rapids, Iowa)
I watched my neighbor install his hardwood deck and thought that I'd never be able to do it myself. But when deciding on what type of deck to install, we decided to use Ipe. I borrowed my neighbor's Hardwood Wrench Jr. and was amazed at how simple it was to use. We also used hidden deck fasteners from DeckWise® and our deck is even better than our neighbor's face screwed deck! Ron Dalton (Charlotte, NC)
As a contractor I do a lot of different jobs and a few decks each year. I purchased the Hardwood Wrench Jr. for my small crew to use and they love it. I'm considering getting another one and maybe expand my deck building more this summer. Pete Kotz (Rugby, Indiana)
